Thermo Scientific™ SPS Disk

Description

• Presumptively identify Peptostreptococcus anaerobius using Thermo Scientific™ Remel™ SPS Disk
• Graves et al
• used a reagent-impregnated disk to determine the susceptibility of anaerobic cocci to SPS
• They reported that amongst anaerobic cocci only P
• anaerobius is sensitive to SPS
• Wideman and Wilkins further verified these findings and reported 98% overall accuracy in the identification of P
• anaerobius isolated from clinical specimens 1,2
• Peptostreptococcus anaerobius is a slow growing, Gram-positive anaerobic cocci (GPAC) bacterium
• P
• anaerobius is an opportunistic pathogen that can cause multiple deep organ abscesses and infections throughout the body, especially in the abdominal cavity and female urogenitary tract
• Use SPS Disk for presumptive identification of Peptostreptococcus anaerobius
• Ready to use - Reagent impregnated disk Easy to store - No special storage required Easy to interpret - Visible zone of inhibition Sensitive - Zone of inhibition equal to or greater than 12 mm Resistant - No zone of inhibition or zone less than 12 mm SPS Disk contains sodium polyanethol sulfonate
• Sodium polyanethol sulfonate (SPS) is a synthetic, heat stable anticoagulant which inhibits bactericidal agents in blood 3
• SPS has also been found to inhibit the growth of certain anaerobic cocci
• The growth of P
• anaerobius is inhibited by SPS
• Positive test (sensitive) is indicated by a zone diameter of 12-27 mm around SPS disk.
